Serial No. 172,704.

e This invention relates to type carriers and more specifically to atype carrier adapted to carry a maximum number of type characters in aminimum of space.

Tn printing machines such as adding machines, cash registers andtabulating machines it is common to provide a series of type elements ona reclprocatmg type carrier or bar movable differentially 1n accordancei With the items to be printed. When a large roup of characters isprovided on each t pe gar the long reciprocating stroke of the ar is animportant factor in the speed of operation of the machine and a savingin time could be effected if the characters could be grouped so that thecarrier need not be reciprocated through too great a stroke. Attemptshave been made to .shorten the stroke of the type carrier by placing thecharacters on the several faces of a square type bar. This necessitatesin addition to the reciprocatory movement of the type bar, the turningof the bar about its. longitudinal axis to present anyone of the desiredfaces for printing. It also necessitates atype of printing deviceWherein the entire type bar is actuated against the platen or in whichthe platen is actuated against the type bar in order to prdduce thenecessary impressions. This type of printing device has not provedsatisfactor and the practice has been to adhere to suc printing devicesas permit of the individual projection of the type elements against theribbon or platen.

Tn my invention ll employ a type carrier wherein the individual typeelements are movable with respect to the carrier and may be individuallyprojected against the platen to eect the printin impression.

The principal o y ject of the invention which `will be obvious from theforegoing statement is to group the printing characters in a short,lineal space with respect to the type carrier so as to reduce the strokeof operation therefof and correspondingly increase the speed of lar typecharacter for printing will not result 1n t e various type elementsbeing out of phase with each other.

Referring to the drawings wherein I have shown what I now consider to bethe preferred form of my invention:

Fig. 1 is a side view of a type carrier with a group of t pe elementsconstructed in accordance wit my invention, a portion of the casingenclosing the type elements being broken away to show the type elementscontained therein.

Fig. 2 is an enlarged detail of the upper l portion of the type carrierwith the front portion of the casing removed to reveal the detail ofconstruction therein.

F Fig 3 is a section taken on line 3-3 of 1g.

4 isi a section taken onf line 4 4 of ig. 5 is a detail of a gear rackemployed to adjust the type characters.

In the drawings the type bar roper is designated as 1 and is providedwit ratchet teeth l by means of which the bar may be stopped indierential positions in accordance with the dierential items on thecontrolling keys, tabulating cards orthe like, in a manner well-known tothe art. The bar has at its upper end a casing 2 within which arecarried a plurality of type elements 3. A coil spring 4 wrapped aboutthe type element 3 an pressing at oneV end against a stop 5 fixed to thetype carrier, and at the other end against a shoulder 6 integral withthe type element 3 serves to retract that e element from its forward oroperative position toits normal position as shown.

The practice heretofore has been to provide each ofthe type elements 3with one printing character at its forward end the element beingpropelled by any suitable bammer from the rear end to project the typecharacter against the. platen to print the character.

lin my invention T have provided an adjustable member 7 here shown inkthe form of a pinion wheel pivotally mounted in the element 3 at 8. Thispinion is shown as having two faces 9 each of which carries a typecharacter 10.l lThe characters on'simi- Alarly disposed faces constitutea predetermined rogressive series as A, B, C, etc. while tliiose on theother faces constitute a dierentseries as 1, 2, 3, etc. for example. Theteeth of the inion 7 are meshed with the teeth of a rac c 11 movablymounted in the casing 2 so that longitudinal movement of this rack upand down with respect to the casing vwill rotate the pinion wheel 7 topresent either of the type faces 9 and type characters 10 in positionfor printing.V Also associated with each pinion 7 is a slide 12having-at its outer end teeth 13 meshing with 15 the pinion. The slidereaches through holes provided for this purpose in the rack 11 so thatthe slide mayl be moved laterally with respect to the rack 11 but isconstrained to move up and down therewith when therack is ,raised orlowered to alter the positions of tljeglpinions 7. Thus it will be seenfrom F1gf'2 that while any one of the type elements areuin advanced orprinting position, movement of the rack 11 up and down will not g5 onlychange the positions of the pinions 7 in' ,mesh therewith but willthrough the movement of the slide 12 also change the position of suchpinions as have moved forward with their type element 3. Thu-s, shouldtherack 3o 1l be moved downwardly in Fia'.` 2 it will turn the two upperones of pinions 7 here shown and will also by moving the slide 12downwardly turn the lower one of the pinions 7. B v this arrangement itwill be seen that it is not possible to accidentally turn any one of thepinions 7 without turning all ofthe others associated therewith andcarried by the same type bar. The rear end of the slide 12 abuts againstthe shoulder 14 of the type element between the walls or brackets 15 inwhich are mounted the pinions 7 so that as viewed in Figs. 2 and 4. whenthe type element 3 is moved forward or to the left with respect to thecasing 2 and the rack 11, the shoulder 14 will move the slide\12 alongwith the pinion 7 so that the slide will be kept in mesh with thepinion. j

The several type elements 3 are spaced from each other by means ofspacing plates 16 which may be bifurcated at theirfother ends as at 17so as to straddle the rack 11 and be held in position thereby.

For convenience `in construction, the rack 11 may be made in two parts11a and 11"; oneof the parts as shown at 11c being recessed to receivethe slide 12, the part 11b then being fastened to part 11a. Theintervening projection 11d will serve to prevent the slide 12 frommoving up and down with respect to the rack.

While I have shown but two type characters 10 on each pinion member 7 itwill be noted that in the present disclosure there is sutlicient spaceon each pinion for an additional type character and it will also beunrelative sizes of .the parts any reasonable number of t'ype charactersmay be provided on each pinion 7.
